This image showcases a well-organized air conditioning training setup, designed to simulate real-world HVAC installation and servicing scenarios. It features a split-type AC system using R-410A refrigerant, with both the indoor and outdoor units mounted on a demo board. The setup includes pressure gauges, insulated refrigerant lines, a compressor, and a manifold gauge set for monitoring and testing. This kind of setup is commonly used in HVAC training centers to help technicians understand the refrigeration cycle, pressure readings, and proper handling of refrigerants during charging, vacuuming, or maintenance.
